External switches installed and connected to the plug
connections 1…8 are allocated to specific functions
by code 23. Some of these functions can be activated
and de-activated. The allocation can be performed to
suit the mechanical mode of operation of the switch
(open = ON, closed = OFF) or by reversing (open =
OFF, closed = ON).
In addition to physically existing switches a logical
“phantom switch” is also available, designated switch
number 9. By allocating this switch to a function, it
can be permanently switched on or off.
As any number of functions may be allocated to any
of the switches, linkages can be achieved for which,
otherwise, mixers would have to be used, which in
this way remain available for other purposes.
Allocation and Pole Reversal of External Switches
After calling code 23, the functions available for the
active model will appear on the upper line of the
display, with the allocated switches appearing on the
line below. Numerals indicate the switches wired to
the corresponding plug stations.
N means that the function in question is de-activated.
Flashing numerals indicate that the switch concerned
has been allocated with reverse polarity. The small
arrow (upper line) indicates the function to which the
switch can be allocated at the present time. It can be
moved to the right or left by pressing the INC and
DEC key, respectively.
As not all of the available functions can be shown at
the same time on the display, the latter can be moved
– window style – over the two lines, showing the
allocations. When the arrow points to the outermost
right function, the next function will appear in the
display when the INC key is pressed. They can be
scrolled left by pressing the DEC key. In this
manner any of the functions can be displayed.
To allocate the selected functions press the CLEAR
key. As a result a question mark symbol will appear
on the lower line. To switch be may allocated by
pressing keys 1 … 9 . If the switch is to be reversed,
the DEC key has to pressed first.
If a de-activatable, currently active function is
selected, pressing the CLEAR key will first de-
activate the function, pressing the CLEAR key a
second time will display the question mark symbol.
The type and number of functions, to which switches
can be allocated via code 23, depends on the
activated model type (code 58).
